1 Claim.

trative embodiment thereof shown by way of example in the accompanying drawing, wherein:

Fig. 1 is a perspective of a fiberboard box having a, corner reinforced by a stay tape exemplifying the invention, partly broken away;

Fig. 2 is a plan view one; larger scale of a fragment of a tape such as is used in Fig. 1 and as viewed from the further side and with parts broken away; and

Fig. 3 is a fragmentary View illustrating a preferred method of manufacture.

The tape shown in the accompanying drawing as an example of my invention embodies a narrow base strip-6 of kraft paper or the like of a suitable width to span the edge of a box, having adhering to one face thereof reinforcing strands 8, preferably, as shown, separate and unreticulated, which extend transversely across at least,

the major portion of its width. Herein I have shown these strands 8 as at right angles to the length of the strip and extending from edge to edge, and the strip 6 with the strands 8 adhered thereto may be cut to a suitable width-from a wide web suitably prepared by methods known in the art, as will hereinafter be referred to.

The ends of the strands 8 are covered by relatively narrow strips iii of paper adhesively secured thereto and to the body strip 6, the opposed edges of the strips l0 being spaced from each other to leave, as best seen in Fig. 2, a narrow central zone I2 consisting of the single thickness of the base strip 6 crossed by the transverse strands 8, the ends of which are anchored in the adhesive joint. between the narrower strips i0 and the base strip. In the complete stay tape, as shown in Fig. 2, the margins are stiffened by the paper strips Iii. which define a central zone between them which is relatively flexible trans versely and permits the tape to be quickly and accurately bent to flt-an angle such as the corner ofaboxasshowninFig, 1. y Y

One side of the tape, as shown in Fig; 2, may be coated with adhesive i4 whichfmay be activated by moistening'or otherwise when the strip is applied to use. or adhesive may be applied when the not restrictive; reference being had to the ap-' strip is used. Herein I have shown the tape as i applied with the narrow strips i 0 presented to the .of the additional strlps.

box so that the reinforcements 8 in the narrow zone i2 between them are protected and covered by the outer strip 6. Whichever side of the tape, as illustrated in Fig, 2, is applied to the article, a smooth surface is provided for its attachment at either side of the central bending zone, while the ends of the strands which are received and anchored between the strips l0 and the strip 6 may be pressed into firm adherence to each other and to the strands during the process of manufacture.

While in the example shown the strands 8 are adhesively secured to the strip 6 at the location of the zone between the strips in and this prevents casual displacement thereof, the joint is a relatively superficial one. Under certain localized strains the strands may free themselves and bunch together by relative movement along the longitudinal line of the tape gradually to take up and resist the strain, which is an advantageous l feature.

full width of a mill roll of paper, may have transeach twice as wide as the strips iii, may be secured over the strands with a suitable spacing between them corresponding to the desired spacing between the strips ill in the completed tape as shown in Fig. 3. .The web may. then be slit longitudinally along the lines a--a to provide a number of tapes such as is illustrated in Fig. 2.

I am aware that the invention may be embodied in other specific forms without departing from .the spirit or essential attributes thereof, 7 and I therefore desire the present embodiment to be considered in all respects as illustrative and pended claim rather'than to the foregoing description to indicate the scope of the invention.
